No, not at all. The first couple of hours were classroom theory. The end of the class you go in back and pick the machines and the process you want to practice on. I got value out of both parts of the class.
The spool gun has a drive system that can be powered off of 115VAC, or a DC supply from the welder depending on which model spool gun you buy. The welding current of course comes from a CV welding supply.
